Lena Dunham’s book proposal shows she doesn’t hide anything about her life, nor does she shy away from public displays of affection. The creator and star of HBO’s “Girls” got cozy with her rocker boyfriend, Jack Antonoff, a guitarist for the band Fun, Sunday outside the Kings Road Cafe. The pair were spotted sharing some food at the Hollywood eatery before sharing a kiss outside. Reports of them being an item sprung up in September. Dunham recently signed the $3.7 million book deal.
